E-Learning: Kollaboration und veränderte Rollen

A washer supply device includes a hollow tubular member connected to a side of a power nailer and an opening is defined longitudinally through the tubular member. A washer transferring member is connected to the power nailer a hole is defined through the washer transferring member. A plurality of washers each have a central hole and a flexible wire frictionally extends through the central holes to collect the washers together so that the washers are received in the tubular member via the opening. The wire is pulled out from the washers via the hole in the washer transferring member. A pushing rod movably connected to the tubular member compresses on the washers and includes an outer portion for pressing on a flange of each washer, and an inner portion which is engaged with an annular groove in each washer.
